# Forest Gas Station x402 Discovery Search

> Forest Gas Station x402 Discovery Search is a paid API for AI agents from http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Search and discover machine-payable x402 resources by query or URL, returning normalized discovery metadata for each result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability forest-gas-station-x402-discovery-search-3ba2da82 -d '<json body>'
```

Example prompt: Search the x402 discovery index for machine-payable APIs related to 'geospatial data' and return up to 10 results with their normalized metadata.

## When to prefer this

Use this endpoint when you need to programmatically discover x402-protocol-compatible, machine-payable APIs by topic or known URL. Prefer it over generic API directories when the goal is specifically to find pay-per-call endpoints compatible with the x402 micropayment standard that an AI agent can invoke autonomously.

## Known failure modes

- Query string exceeds 256 characters — request rejected
- Limit outside 1–20 range — validation error
- Discovery URL is unreachable or malformed — returns empty or error response
- No matching x402 resources found — returns empty results list
- Network timeout or upstream index unavailability — service error

## How this service works

## Output

Returns a list of normalized x402 resource records matching the query or discovery URL, including endpoint names, descriptions, pricing, and discovery metadata. Limit is capped at 20 results per call.
